1. **State the problem:** We have a parametric curve defined by the equations:
$$x = 9 + 2t^2$$
$$y = 4t$$
with the parameter $t$ ranging from $0$ to $2$.
2. **Goal:** Understand the shape and position of the curve by analyzing the parametric equations.
3. **Express $y$ in terms of $t$:**
$$y = 4t$$
4. **Express $x$ in terms of $t$:**
$$x = 9 + 2t^2$$
5. **Eliminate parameter $t$ to find $y$ as a function of $x$:**
From $y = 4t$, solve for $t$:
$$t = \frac{y}{4}$$
Substitute into $x$:
$$x = 9 + 2\left(\frac{y}{4}\right)^2 = 9 + 2\frac{y^2}{16} = 9 + \frac{y^2}{8}$$
6. **Rewrite the equation:**
$$x - 9 = \frac{y^2}{8} \implies y^2 = 8(x - 9)$$
7. **Interpretation:** This is a parabola opening to the right with vertex at $(9,0)$.
8. **Parameter range:** Since $t$ ranges from $0$ to $2$, $y$ ranges from $0$ to $8$ and $x$ ranges from $9$ to $9 + 2(2)^2 = 9 + 8 = 17$.
9. **Position hint (top-left):** The curve starts at $(9,0)$ when $t=0$ and moves to $(17,8)$ when $t=2$, moving upward and rightward.
**Final answer:** The parametric curve is a right-opening parabola segment from $(9,0)$ to $(17,8)$ described by
$$y^2 = 8(x - 9), \quad 0 \leq y \leq 8.$$
